Extracts of submerged cultures of a
Stereum species afforded four new pentasubstituted phenolic compounds, named hericenols A, B, C, and D (
1–
4), 6-hydroxymethyl-2,2-dimethylchroman-4-one (
5) and the known erinapyrone C. Hericenol A (
1) showed weak antimicrobial activity while hericenol C (
3) was weakly cytotoxic. The structures of the metabolites were determined by spectroscopic techniques.
Four substituted phenols, e.g. hericenol A (
1), were isolated from fermentations of a
Stereum species.
